Application filed June 16,1909. Serial No. 502,631.

To all whom it may concern l Be it known that I, Or'ro PETERMANN, acitizen of the Republic of Switzerland, and a resident of New York,county and State} of New York, have invented certain new and usefulImprovements in Carriages for of which the following 1s a full, clear,and exact description.

This invention relates more particularly to carriages of foldable frontstrike or visible typewriting machines.

The primary object of the invention is to provide simple and efficientmeans serving as a ball bearing connection between the carriage and itssupport, so that the latter may move freely in either direction alongthe support; to provide means which will so hold the carriage that itwill be substanthereon to properly take the impact of the type againstits surface, and to provide a simple and efficient connection betweenthe balls so that the said balls may move in unison-and be held properlyspaced apart.

Another object of the invention is to provide a simple and efficientcarriage which may be used for different forms of typewriting machines,and which will be properly guided during its movement along its support.

A further object of the invention is to provide a simple and efficientmachine in which the carriage and support or frame may be elevated todifferent heights, and which is adapted to be folded over above thekeyboard of the machine.

With these and other objects inviiew, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which-form a part of this specification, and will then be pointed out inthe claims oat the end of the description.

in the drawings, Figure 1 is a longitudinal. section, partly inelevation, of one form of machine embodying my invention. Fig. 2 is arear elevation; and Fig. 3 is a detail perspective view of the guideforming a part of the ball bearing for the carriage.

The machine hereinafter set forth is of the type shown in the patent toFrank S. Rose, Serial No. 754,242, patented March" 8th, 1904. inwvhichthe carriage is adapted ing member or bed 25.

to be folded over above the keys, and while in the present invention thecarriage and platen and their operating mechanism are adapted to beraised and lowered. on the frame of the machine and to be folded overabove the keys of the key levers and in which the type-bars have a frontstrike for visible writing, it is to be understood that the features ofthis invention may be used in connection with other classes of machines.

The metallic frame 10 of the machine is constructed and arranged in anysuitable manner and may consist of side. members and an integral backmember 11. An intermediate transverse horizontal bar or plate 12 issuitably fastened to the side members of the frame and serves as a bracetherefor, and at the front of transverse bar 13, the whole frame beingconstructed of sheet, metal with rounded edges or otherwise for thepurposeof making the frame light and strong.

.A slide 14 is hinged at 15. to" an extension 16 of the frame or support17, there being a slide and an extension at each side of the machine.The machine is provided with key-levers and with one or more shiftlevers. 18 for elevating the slides 14. A flexible th machine isa'second connection 19 leads from a spring drum-20 and servesto forcethe carriage along the bed in the usual way. The drum is mounted uponthe support 17 and forms a part of the carriage feed mechanism, theescapement mechanism not being shown, and this mechanism as well ascertain other features together with mechanism for the line and letterspacing is of any suitable construction.

The carriage 21 is provided with a suitable frame 22, and this' framehas a iorigie tudinally-extending member 23, and mounted on the carriageis a suitable platen 21 and operating mechanism for said platen. Asecond fixed member or bed 25 is held to the support 17, and extendingtransversely of the machine are suitable guiding means for the carriage.These members 23 and 25 are cut away to provide grooves on their opposedsurfaces on each side of the longitudinal center of said members, Asshown the member 23 is provided with a groove 26 on each side thereofand these grooves are opposed to the grooves 27 formed in the upper faceof the stationary and support- These. grooves are located in the samehorizontal plane and may be slightly tapered vertically and form tworace or track-ways, and in the outer race-way are a plurality of b llsor other anti-friction objects 27 and' in the inner raceway a singleball or anti-friction object. The halls are connected b a device 29, andsaid device may be made of a single 'piece of wire having guides 30 inthe form of loops for the balls 28 of the outer raceway. The guides 30pass around the balls in which the latter-are loosely mounted, and saidguides are connected by the bot y portion or part 31, as shown best inigs. 2 and 3. This device 29 has a single loop 30 which is connected atone end of the device adjacent to one of the guides by an integralangular body portion 31. The guides t0 and 30 are located in the samehorizonta plane, the part or guide 3O being adapted to hold loosely asingle ball 28 which is positioned substantially central of the twoguides 30 of the outer race-way. The device 29 serves. to hold the balls27 spaced apart to move in unison, and the balls serve to form a properbearing for the carriage so that the latter may be properly guided inits movement across the machine.

In this application I do not claim the escapement mechanism, and certainother features of a complete machine as the same are clearly set forthand claimed in other pending applications filed by me.

From the foregoing it will be seen that simple and efficient means areprovided whereby a ball bearin connection may be madebetween thecarriage and its support so that the latter may move properlytransversely of the machine; that said bearing is so connected that theparts thereof may move together, and that the arts of the carriage areso mounted that t e same may be elevated to various positions and alsoto be folded over above the keys when not in use.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a typewriting machine, the combination of acarriage bed rovided with grooves along its upper sur ace lengthwise ofthe carriage on opposite sides of the longitudinal center thereof, acarriage adapted to move along said bed and having a plate portionlocated above the bed and having grooves on its under surface lengthwisethereof opposed to the grooves of the bed and forming therewith twoparallel and horizontally arranged race-Ways, a plurality of ballsarranged in one of the race-ways, a single ball arranged in the otherrace-way, and a tie device loosely holding the balls to cause them tomove in unison.

2. In a typewriting machine, the combination of a. vertically movablecarriage bed provided with grooves along its upper surarranged facelengthwise of the carriage on opposite sides of the longitudinal centerthereof, a

carriage adapted to move along saigLbe'd and having a plate portionlocated above the bed and having grooves lengthwise thereof opposedtothe grooves of the bed and forming therewith two parallel andhorizontally arranged race-ways, a plurality of anti-friction objectsarranged in one of the raceways, a single anti-friction object arrangedin the other race-way and a horizontally arranged integral wire tiedevice loosely holding the objects to cause them to move in unison.

3. In a typewriting machine, the combination with a bed provided withhorizontally rooves along the upper surface thereof, 0% posed to the bedand also having grooves opposed to the grooves of the bed and formintherewith race-ways located on opposite sit es ofthe longitudinal centerof the carriage, a plurality of balls arranged in one of the race-ways,a single ball arranged in one of the race-ways, and an integral'wiredevice having aplurality of guides in the form of loops adapted to fitloosely about the balls in one of" the race-ways and having an angularportion'extending from one of the guides at one end of thedevice andformed into a single guide at the end of said angular portion which islocated substantially central of .the first-mentioned guides and in thesame plane therewith.

4. In a typewriting machine,ithe combination of a bed provided withhorizontally arranged grooves along the upper surface thereof, acarriage having a plate opposed to the bed and also having groovesopposed to the grooves of, the bed and forming therewith race-wayslocated on opposite sides of the longitudinal center of the carriage, a

a carriage having a plate opplurality of balls arranged in one of therace-ways, a single ball arranged in the other race-way, and a devicehaving a, plurality of guides in the form of loops adapted to fitloosely about the balls in one of the race-ways and having a guide forthe single ball located substantially central of the firstmentionedguides and in the same plane therewith.

5. In a typewriting machine, the combination. with a bed provided withhorizontally arranged grooves along the upper surface thereof, of acarriage having a plate opposed to the bed and also having horizontallyarranged grooves opposed to the grooves of the bed and forming therewithrace-ways located on opposite sides of the longitudinal center of thecarriage, two balls arranged in one of the race-ways, a single ballarranged in the otherrace-way and a device having two ,end gnides'in theform ofloops adapted to fit loosely about the balls in one of therace-Ways and having an angular portion extending from one of the guidesat one end of. the device and This specification signed and witnessedthis 4th day Of June, A.
